A, B, C... are the ID of the problems (not sorted by difficulty, teams have to figure out the order).

For each cell of (team, problem), the "ratio" x/y isn't actually a ratio. x means how many submissions were made. y is the minute when the accepted solution was submitted. For example, "3/298" means they made 3 submissions in total, and the accepted solution was submitted in the 298th minute (the contest lasted 300 minutes).

The penalty ("Time" column) is calculated as (sum of y) + 20 * (sum of (x-1)).
